The statement comes after QPR manager Mark Hughes on Tuesday spoke to Anton Ferdinand to ascertain his state of mind ahead of the Loftus Road FA Cup tie, which is set to bring him face to face with John Terry.

It will be the first time the pair have met since Terry was charged with racially abusing Ferdinand in October’s derby in the Premier League, which QPR won 1-0 and during which Chelseahad two players dismissed.

Terry is scheduled to attend West London Magistrates Court next Wednesday after being charged with a racially aggravated public order offence, with the trial expected to be adjourned for six to eight weeks.

The timing of the tie, however, has caused concern at both clubs who are anxious to calm matters between the two sets of supporters. On police advice, the match will kick off at noon.

Contrary to claims on Tuesday, Ferdinand has not been urged by QPR to shake Terry’s hand during the customary pre-match 'fair-play handshake’. Instead QPR regard it as Ferdinand’s personal choice and have no intention of putting pressure on him.

The defender spoke to Hughes after training on Tuesday with the manager anxious to find out his feelings, rather than encourage a reconciliation with Terry. QPR are adamant the decision rests with Ferdinand, although the likelihood is that the 26 year-old will shake Terry’s hand.

However Ferdinand is anxious for this not to be presented as some kind of acceptance and to make sure that what he says or how he acts does not prejudice the forthcoming case.

He has impressed staff and management at QPR with the way he has handled himself since the alleged incident.

Terry has vehemently protested his innocence and will continue to do so and has told Chelsea that he would like to shake Ferdinand’s hand. He has attempted to speak to Ferdinand, but his overtures have been rebuffed, while his claim that the pair had cleared the air, immediately after the match, has been rejected.

Ferdinand did not make the complaint against Terry — that came from a member of the public which triggered the police involvement — but was later shown the video footage of what allegedly happened.

The QPR players have been given on Wednesday off but it is understood that Ferdinand will also speak to the club’s chairman, Tony Fernandes, as he considers what to do on Saturday.

The statement from the two clubs will involve Fernandes and Chelsea chairman Bruce Buck and will remind supporters that it is appropriate to focus on what is an FA Cup tie, a London derby and a match that is keenly anticipated around the country, for football reasons.

They will ask the fans to reflect everything that is good about the clubs and not to abuse either player.

Feelings have continued to run high since the alleged incident. A Chelsea supporter was arrested earlier this week on suspicion of racially abusing a woman at Liverpool Street station after returning from last Saturday’s league match at Norwich City.

Hughes will hold his weekly press briefing on Thursday, and is expected to deliver a similar appeal, with Chelsea returning from their midseason break in Majorca the same day. On Friday, Chelsea manager Andre Villas-Boas will speak to the media.

QPR on Tuesday completed the loan signing of AC Milan defender Taye Taiwo until the end of the season. The 26-year-old Nigerian international left-back is Hughes’s first signing since he was appointed two weeks ago.

However there was a blow for QPR with Alex set to sign for Paris St-Germain, coached by Carlo Ancelotti, after he failed to agree personal terms.

QPR have also been thwarted in their attempts to acquire Brazilian striker Henrique, after a work permit was refused, but are still attempting to sign Blackburn Rovers defender Christopher Samba and Manchester City’s Nedum Onuoha.
